PROCESS FOR MAKING AND FILLING-BAGS. I

Application filed October a, 1919. Serial No 328,309.

To all whom it may concern Be it known that I, ADELMER M. Barns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Processes for Making and Filling Bags, of which the following is a specification. My invention relates to a process of making and filling bags, wherein a tube is first made from a rollof material and then either after or during the process of making said tube the material is fed" by successive charges into the tube and the tube sewed and severed so as to form by a more or less continuous process a series of complete filled bags.

It will be understood that the tube. mak ing process is or may be a substantially continuous process, whereas the bag filling and severing process must in the nature of things be an intermittent process, and my invention makes it possible to correlate andv properly time the tube making and the bag filling, closing and severing acts. This is done by having a storage or lost motion space where the bag tube is puckered up and held after it is formed, so that there is an appreciable length of bag tubing always in storage or standing between the tube forming part of the apparatus andthe bag closing and severing part, so that either part of the process may slow up or even cease completely for atime without affecting the continuance of the otherpart' ot the process. e

I have shown, diagrammatically, tube forming, closing and severing devices associated in such manner that my process could be carried out continuously thereon, but of course this is all diagrammatic and the process could be carried out by other mechanism or in part by hand.

In the drawing, the figure is an elevation of a diagrammatic showing of means for.

' tion of the tube.

its two edges together, and upward on the outside of which the fabric passes and downwardthrough the inside of which the finished tube passes. G is a sewing machine bywhichthe two edges of the fabric are united. i

J is a funnel into which, successively, measured. charges of material can be deposited in any desired manner.

, K is a feeding tubeleading down from said funnel and extending any desired dis tance withln' the bag forming tube and the bag tube. V

L is a table or platform' onwhich'the N is :a'tube sewing and severing apparatus, past which the lower end of the tube is adapted to be moved. In the preferred method of operating, two seams are run across the tube above the charge, which lies in the end of the tube. These two seams are close to each other and they are run from one side of the tube toward the other either by moving the sewing apparatus or by moving the tube. The severing apparatus is preferably in the'rear of the seaming device, having reference to the direction in which all three are moving across the tube; All these parts are shown diagrammatically. I

O'is the severing apparatus andP P the two needles' or seam forming devices. p

Q indicates in dotted lines the lower free tube portionadapted to be moved laterally, andR indicates a puckered or gathered porr Inthe preierred'process, there isa considerable distance between the upper end of the'bag tube and the lower.

end thereof, and a considerable portion of the intermediate part of the tube is puckered. The feeding tube may be varied in length, but it preferably extends well down toward the lower end of the bag tube, and

means R are preferably provided for expanding the bag tube at this point.

S is an elastic band about the supporting or feeding tube, beneath which the bag tube bag on the lower end of thetube may rest. I

passes so that it is suspended in part at that point,;with a puckered or collapsed portion 'ofthe bag tube above it.

The bag tube, formed with the seam sideor outside and with or without the forming tube or the storing or feeding'tube,

is suspended and manipulated'in any convenient manner, as set forth in the description of the process.

It will be understood that various features or steps or" the process may be omitted and that the order in which they are performed may be somewhat varied and that my drawings are strictly diagrammatic.

The use and operation of my invention are as follows p I first provide myself with a roll of mate rial which may or may not be printed. The

edges of this strip er" material are brought together in any p )er int-b11381, as for example about a forming tube, and they are sewed together. thus rorming a tube. This tube is supported in any desired manner. In the drawing, T have shown it supported by the upper edge the forming tube, the dei ice R and the device S. An one may be suiiicient, or all of the means re' erred to, or any two of them, may be required to iroperly support or suspend the bag tube. By support or suspend such action. as holds the tube in the operative relation desired. I

There are two separate feeding movements, the one which carries t ric past the tube forming apparatus 8.116. the irregular feeding movement by which the forming end is moved ii'orward or downward the momentum of the large, or by hand, or by both, or by any other agency. These two movements cannot be synchronized; hence the need of two independent feedin' movements one to form the tube h 7 and the other to draw out the tube to form the bag. The bag tube is fed downwardly in any desired manner, hutiny preferred proc ess involves feedingit downwardly by actioh oi the successive charges of material dropped into the closed end of the tube; The length or the bag; tube from the point where the material is dropped into it to the bag end should be considerabie. in order to give effect to such feeding action on the part of the successive charges of material. when it is desired tol'ely upon this for feeding th tube downwardly. using; the charge itself to feed the fabric forward I. can avoid the use of special feeding niechanisu'i or the effort required to pull the tube down by hand. The transverse stitchingof the fabric to close the top of one bag id the bottom of the tube is carried on from one side to the other of the tube, either 1 swin. {I the tube or the stitchi mechanism. or both. tiii e there is an extended length oi tube int euino; between the point where the charge is introduced and th bottom of the tube, an appreciable interval. will transpire between the instant when the chargre is introduced and the instant when it strikes the *iower tube portion may be facilitated, and

the ope-r ions or making the seam which forms the tube and stitching and severing the tube transversely do not have to be synchronized. Either may proceed. independently of the other, or both simultaneously, and their respective speeds may be varied.

The material used may be any desired bag fabric ar l any suitable method of closure may be used. T have illustrated the invention by applying it to cloth, using stitched seams and turning the tubing.

Spee is extremely important wh'ere enor mous quantities of bags to be made and filled. To a considerable degree, the object of my in. ition is to produce a method or process which will permit the greatest practicable speed. My invention is in part ap piicable to the e where a tube is made and 1nd iater made into filled and s'e'vh as, but the invention is also applio the case where the process of makingr, filling and separating the individual, bags is in a sense coincident with or carried on duri the formation of the bag tube. in the latter case, when starting on a new roll of cloth the tube forming process will continue long enough to provide a su'fiic'ieiit amount of tube to take care of any difference in ogeration the two parts of the ma chine, and this storage amount of tube is intained more or less constant, increasing or diminishing as the speed or": the twooperations at any time may tend to vary.

The severing device preferably travels in the rear oi? the closing devices, and this will be true even if the material is paper and'the closing devices operated by means of g urir mine' the fabric together. If the severing of the tube between the two closures is not performed behind or in the rear of the for mation of the closures, the bag material is likely to be distorted and this is particularly true where, as in the preferred method (if operation, the bags are formed with an eitoeedingly short portion of bag rhati'ialprojecting eyond the seam or closure.

It paper is used tor the bag materialinstead of fabric, then I may substitute for the needle and sewing machine means for pastingor cementing the edges of paper to- QQtllGl, and under some conditions such pasting means might be applied to the cloth fabric. So far as my process is concerned a tube and bags made of pasted paper or pasted fabric would be practically the same tubes and bags made of sewed fabric.
